Genesis 3:15

Thou shalt bruise his heel.—This is your hour, and the power of darkness.—As the children are partakers of flesh and blood he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil, that is, the devil.—Having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.

Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about seeking whom he may devour: whom resist stedfast in the faith.—Resist the devil, and he will flee from you.

This is the first promise to fallen man. It contains the whole gospel and the essence of the covenant of grace. It has been in great measure fulfilled. The seed of the woman, even our Lord Jesus, was bruised in His heel, and a terrible bruising it was. How terrible will be the final bruising of the serpent's head! This was virtually done when Jesus took away sin, vanquished death, and broke the power of Satan; but it awaits a still fuller accomplishment at our Lord's second advent and in the Day of Judgment.

To us the promise stands as a prophecy that we shall be afflicted by the powers of evil in our lower nature, and thus bruised in our heel; but we shall triumph in Christ, who sets His foot on the old serpent's head. Throughout this year we may have to learn the first part of this promise by experience, through the temptations of the devil and the unkindness of the ungodly, who are his seed.

His visage was so marred more than any man, and his form more than the sons of men.—He was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.

This is your hour, and the power of darkness.—Thou couldest have no power at all against me, except it were given thee from above.
